Starting with firmware version 19.5.0, the firm has now chopped the tensor core count on Blackhole p150 cards from 140 to 120, affecting both new cards and existing units already in customers’ hands. > > The news was apparently communicated to customers via email, with the same wording present on the firmware update’s GitHub page. Tenstorrent isn’t elaborating on why the change was made, leaving existing and potential buyers scratching their heads
